Lawyer change

Dear Legal Experts, We have given application for lawyer change to the court and the court has not given us permission to change the lawyer. Our earlier lawyer has taken money from the opposite party and has misrepresented the property suit on partition. The judge has been transferred and supposed to join new court on 3 June. She has taken this case on board even if we don't have a lawyer, neither she is giving permission to change the lawyer. She has given order for money withdrawal to the opposition. The lawyer has refused to give us NOC and asking for 10% of the property. He has also threatened our family for consequences. When we asked her why she is not giving us permission for lawyer change, she started shouting at us in open court. We were shocked to see her behaviour. The court proceeding is happening in a senior district court. They are proceeding in a civil suit even during summer vacation time. The court keeps changing the date without informing us in any way. The judge is ethically compromised and there have been past complaints of biased action at her end. please suggest us correct course of action in this case.
